K&N Releases Air Filters for NASCAR Truck & Busch Series Racers

One of the nation's largest and fastest growing sports is NASCAR. As consumers flock to races and drivers continue to wow the spectators, K&N Engineering has discovered a new niche market with new 2-ply cotton un-oiled filters designed for NASCAR series racers.

NASCAR (stock-car and truck) racers have a choice of K&N's new replacement air filters (E-3024R, E-3025R, E-3026R, E-3027R, E-3028R, E-3029R, E-3030R, E-3031R). "The 14 inch round filters are for the NASCAR Craftsman Truck Series and the NASCAR Busch Series; The16 inch round is for the NASCAR Nextel Cup Series," said K&N Engineering Sports Marketing Director Charles Maier. "We offer the new filter to teams in quarter inch increments from 3, 3 ¼, 3 ½, 3 ¾, and 4 for both the 14 and 16 inch filter." There are 5 of the size 14 and 5 of the size 16. Eight filters are available now and two more will be available soon.

NASCAR rules require air filters in order to race. K&N's new 2-ply cotton un-oiled filters meet NASCAR requirements. "The 2-ply cotton works the same as our 4-ply," said Maier. "It just allows more air to flow."

"K&N is not trying to convince the racing teams by telling them our product is better," said Maier. "We're building the best air filter and letting the teams decide for themselves, and when they see their racers are running better they'll know our product is no snake oil." K&N makes a quality filter and many of the racers do not have to be convinced.

Many of the organizations that sanction Go Kart racing have gone to air boxes due to noise restrictions. K&N Engineering developed an air box for Karts that accepts one of two K&N washable/reusable High-Flow Air Filters.

Our K&N filter (RU-5006 or RU-5005) snaps into the RK-1000 Kart Airbox, next, the whole assembly is clamped on to the carburetor. The K&N Kart Airbox uses a 2 ½" (inside diameter) straight or 20 degree angled-flange High-Flow Air Filter for your 2 or 4 cycle kart. The RU-5006 features a 20 degree angled flange that is 1.5" in length and the RU-5005 offers a straight flange that is 1.5"in length.

In most cases, our K&N Kart Airboxes can be mounted onto the carburetor. Typically, 2-cycle engines have only one cylinder and range in size from 100cc to 125cc.

Some of the 2-cycle engines used in karting can reach around 19,000 RPMs and produce up to 40 HP. Some classes use larger engines, with up to a 250cc displacement.

"K&N Engineering has a history of providing higher air flow and performance gains with increased air flow, "said K&N Engineering Powersports Brand Manager John Jump. "K&N's Kart Airbox is pretty universal, built to the specifications of racing organizations except it holds a K&N Air Filter."

With the addition of K&N's new 77-Series High-Flow Performance Kit (77-9028KP) 2005, 2006 Toyota Tundra owners can realize an 8 + horsepower gain.

K&N engineers were able to put a bigger filter and heat shield under the hood because of the Toyota's extra space under the hood.  K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow.  This allows your truck's engine to utilize a larger volume of air than the OEM air filter assembly. More air means more power and torque when you need it.

The 77-Series Intakes show-quality appearance has under-the-hood style with a polished aluminum finish perfect for the Toyota Tundra.

Our 77-Series Intakes are designed to be installed with simple hand tools in under 90 minutes, are street legal in most states and include the famous K&N Million Mile Warranty®.

Add Power and Style to the 2006, 2007 & 2008 Honda Ridgeline with New K&N Air Intake

K&N Engineering has a polished aluminum 77 Series Air Intake (77-3515KP) available for the truck that defies convention. K&N tests have shown a horsepower gain of 9.70 @ 5159 RPM with this intake.

The intake, like all other K&N intakes, was engineered specifically to work within the Ridgeline's computer specifications while maximizing power and allowing air to flow with little restriction. The large cone K&N air filter and aerodynamic tube removes much of the restriction caused by the factory intake and allows a massive amount of air into the engine; this in turn translates into power. The intake has a shiny polished tube for a great look on the Ridgeline's engine.

Our engineers also took advantage of the factory fresh air duct on the 2006, 2007 and 2008 Honda Ridgeline. The factory fresh air inlet in the bottom of the engine compartment guides cool outside air into the intake track. The heat shield has an opening that allows the fresh air intake duct to feed air to the K&N high-flow air filter. The air filter is isolated from high engine temperature by a heat shield which aids in increasing horsepower.

It takes about 40 minutes or less to install this kit and the oversize lifetime K&N air filter performs for up to 100,000 miles before service is required depending on driving conditions.

Polished Aluminum Air Intake Released for 2004 & 2005 4.6L Ford F-150 Pickup

If you own a 2004 or 2005 Ford F-150 pickup with a 4.6L engine you already know it's one of the best selling vehicles in America. K&N Engineering has met that marketing demand by releasing a new 77-Series intake system, part number 77-2557KP.

K&N tests have shown a horsepower gain of 9.31 @ 4724 RPM for this intake. You may especially feel this added power and torque when accelerating and when towing a load with this truck and air intake.

The F-150's engine compartment size allowed our engineers to utilize a large 6 inch filter.  This also allowed a bigger heat shield.  K&N also added a big radius filter adaptor that helps maximize power and allows air to flow with little restriction.

We usually test at least 3 vehicles for each intake system, but this time we used 5 Ford 150s. K&N Engineers made sure the design provided maximum power to meet consumer demands. There is also a polished aluminum finish on this K&N 77-Series intake system.

The filters on our air intake kits are washable and reusable. It takes about 90 minutes or less to install this kit and the lifetime K&N air filter performs for up to 100,000 miles before service is required..
